Problems solved by technology

[0004] At the same time, risks such as electrolyte leakage and heavy metal diffusion are prone to occur during the lithium battery recycling process. If the battery is manually disassembled, there are safety hazards such as electrolyte corrosion of hands or inhalation of HF gas that is harmful to health.
At present, the recycling of waste lithium batteries mainly relies on physical crushing and chemical extraction. The above-mentioned recycling technologies have defects such as high energy consumption, easy to produce secondary pollution, and incomplete separation and recycling.

Abstract

The invention belongs to the technical field of electronic waste recycling, and discloses a lithium battery core package decomposition device and method. The lithium battery core package decompositiondevice comprises a clamping mechanism for clamping a core package, a cutting mechanism for cutting off a pole piece, a pressing mechanism for pressing one end of the cut-off pole piece, a reverse winding mechanism for unfolding and pressing the other end of the pole piece, and a separation mechanism for adsorbing and separating the unfolded pole piece. Through mutual cooperation of the clamping mechanism, the cutting mechanism, the pressing mechanism, the reverse winding mechanism and the separation mechanism, the lithium battery core package can be automatically and independently disassembled.

Description

technical field [0001] The invention relates to the technical field of electronic waste recycling, in particular to a lithium battery core pack decomposition device and method. Background technique [0002] The production process of lithium batteries is mature, the packaging cost is low, the yield rate of battery products is high, and it has the advantages of high energy density, good safety, and good consistency. With the extensive application of lithium batteries, lithium batteries are about to usher in a peak of scrapping. How to dispose of these scrapped lithium batteries has become a problem that cannot be underestimated. [0003] The main part of the lithium battery is the core pack, and the main part of the core pack is the pole piece. When assembling, it is placed in the order of positive plate-diaphragm-negative plate-diaphragm from top to bottom, and is wound into a battery core pack. The core is packed into the battery shell, and then the electrolyte is injected,...
